Today I was blown away by the David Rumsey Map Collection. David Rumsey has dedicated an incredible amount of time and energy to digitizing and sharing his amazing map collection. I felt truly lucky to go there and touch it though.

Architect Daniel H. Burnham created this map in 1904 as part of a proposal for the beautification of San Francisco. The plan stepped away from the traditional grid that many American cities adopt. Burnham’s dream was never realized because of a lack of funding.
